Russian President Dmitry Medvedev says the United States and Russia have made "significant" progress towards a new nuclear disarmament treaty.
State news agencies today quote him as saying "we have taken a fairly serious step forward, and to a significant degree we have brought our positions closer."
U.S. and Russian negotiators have been in lengthy talks on a replacement for the 1991 Strategic Arms Reduction Treaty (START), which expired in December.
U.S. President Barack Obama and Medvedev have pledged to replace START, which imposed strict limits on their countries' nuclear arsenals, but the talks have gotten bogged down amid disgreements over missile monitoring.
